STOVE.

SPEGIFICAT IQN forming part of Letters Patent No. 401,889, dated April 23, 1889.

Application filed November 23, 1888- $eria1No. 291,690. (No model.)

drawings, wherein-- a I a o Figure 1 1s a view 111 elevation of my 1mproved stove, and Fig. 2 a central longitudinal vertical section showing its relation toand adjustment within the recess or concavity of a summer-piece set in the fire-place of the room to be heated.

My invention relates specially to what is known as a low-down coal-stove, ora stove adapted in height and other dimensions for being set in the modern fire-place, in which the before-mentioned recessed fire-place summer-piece is set. This character of stove as improved by me will-comprise the usual castiron ash-pit section, A, and middle sheet-iron section, B, fitted to the foot-rest a and lined with fire brick, r, and provided with a grate,

a, and adapted to serve as a fire-pot in which the fuel is burned. This latter section is surmounted by an annular conical cast-iron ring,

E, having properly-spaced air-supply and illuminating openings 6 all around it, and is encircled by a draft-regulating ring, e, having corresponding openings, 6 all around it, said ring fitting in a guide of the foot-rest a of the ring E, as shown.

If desired the footrest a and the may be cast in one piece.

On the ring E is mounted an upwardlyflared top section, G, of sheet-iron, which is capped by a hollow conical cast-iron cap portion, G, comprising a ring,E, having air-supplying and illuminating openings c all around it, which ring is encircled by a movable draftregulating ring, 6 having openings e corresponding to those e all around it.

Above the openings ofthe ring E the cap G is made to form an extension or top gasring E chamber, and in the center of the top of the casting a fuel-supply opening, covered by an urn, g, or other device, is provided. The cap 1 G below its openings spans the horizontal area of the entire sheet-iron body portion 0 of section 0, and serves, in connection with the space within the said body portion, as an upper gas reverberatory, combustion, and illumination chamber immediately between the perforated rings E E, as well as above the ring E. To accomplish the combustion of the gases between two rings, E E, the draft exit f of the stove-pipe collar f is located about midway between and in contiguity with the two series of draft-supply and illumination openings 6 e of the sections B and O, as shown, so that the force of the lip-chimney draft shall be sufficient at all times to pre vent the escape of gas into the room through said openings when they are left fully open and the pressure of rising gas is very great. The operation of the stove is similar to other stoves which are supplied with air above the fuel and the starting-draft below the fuel is closed, this operation being the passage of the cold air through the openings 6 6 down to the fuel on the grate and the passage up of the hot air and gases to the exit passage f.

The cap G may be made with a finishing skirting, as a and the sheet'iron body portion may be bolted to an inner flange of the cap, so as to have itsupper edge covered by the skirting. The draftregulating ring E may also have a similar skirting and the same ride on the skirting 0, The stove thus consiracted of a base, middle, and top section is adapted to be included within the dimensions of the metallic concaved or recessed reflecting summer-piece B, Fig. 2, which is fitted to the fire-place opening of a modern chimney. The summer-piece R has a collar, f to receive the collar f of the stove. This summer-piece is made of metal, and may, if desired, be polished on its arched surface opposite the upper illumination-openings, so as to more ef fectually reflect the light and heat into the room.

It will be seen from aforegoing description that by providing the stove with the section 0 and combustion reverberatory cap section G and the air-supply and illumination openings e c all around a high degree of heat will be-secured at the top of the stove, and this heat, being radiated against the arching portion 8 of the summer-piece R, will be reflected outwardly and downwardly into the room, and thus the available heat of the stove greatly magnified and made available for heating the room, and at the same time the illumination will also be increased, from the fact of the flame being exposed all around through the openings in the air-supply and draft-regulating rings of both sections B and O, and the light emitted through these openings thrown upon the concave reflecting-surface of the summer-piece and reflected into the room.

My stove as constructed is quickly heated, and is in many respects superior to known stoves of this class, and its main peculiarity I 5 of having the draft-exit between the two series of air-supply openings makes it possible to utilize the full draft of the stove for preventing the escape of gas at the openings c e ofthe rings E E into the room, while at the same timetlie entire upper section, 0, including the'cap'portion G of the stove, is made to become an illumination, reverberatory, and gas-combustion chamber in addition to the fuel-section B; X I claim- 1. The combination of the concave arching summer-piece B and a single-cylinder fireplace coal-stove having only a direct-draft exit, f, and formed of sections A B 0, sections B and 0 being each provided with a station- 0 ary perforated draftrring and with a sliding perforated downdraft register-ring, said rings being respectively below and above the draft exit f of the stove and all around sections B and C, and throwing light upon the curved surface of the said summer-piece and into the room, substantially as described.

2. A single-cylinder fire-place coal-stove, having only a direct-draft exit, f, and formed of sections A, B, and O, the sections B and O being provided each with a stationary perforated downdraft-ring and with a sliding perforated downdraft register-ring, said rings being respectively below and above the draftexitf of the stove, and exposing thefiaine'of both sections Band C, substantially as'and for the purpose described."
